• Materialized view, based on the stored procedure

  Hi all

  is it possible to create a materialized view on the results returned by a stored procedure?

  If this is not the case, do you think that any other way except for filling a table with data from the stored procedure and then founded the MV on it?

  Thanks in advance.

  No it's not.

  REF CURSOR don't store data, so it's not possible.

  A Ref cursor is just a pointer to a query... and you can't "select from" a ref cursor, you can retrieve only one open.

  PL/SQL 101: Understand the Ref Cursor

  As correctly stated above, you can't question from a procedure to a function, and a materialized view is based on a query, you cannot use a procedure in a materialized view.

  You could use a function pipeline instead of a procedure, or have the pipeline function obtain the results of the procedure and pipelines, and then the materialized view could be based on the results of this function in the pipeline.

  example of function pipeline:

• Dynamically create checkboxes based on a value in a table

  Hi friends,
  
  I am looking for crerating several checkboxes based on a value in the table. For example if I'm clicking on a name of 'material' in a report, I need to show all interfaces for equipment like the checkboxes in another page. There is a table that contains interfaces corresponding to a particular equipment. The box should be checked if this particular interface is "put into service". This info is present in the table "provisioing. How can I achieve this. Help, please.
  
  
  Kind regards
  TJ

  The display order of your boxes depends on your SELECT statement, just put an ORDER BY in there, and you can do whatever you want.

  Don't forget: the LOV-statement must select all of the possibilities, with the process, you set the provisioned to checked.

  brgds,
  Peter

• Impact on performance at the addition of materialized view logs at the tables?

  I write a very complex query for a client of our database system transaction and this will require the creation of a materialized viewbecause, all attempts at development to make acceptable performance failed.
  
  I want to activate the fast refresh the MVIEW but I am confused about the consequences of the addition of the addition of materialized view logs to the base tables.
  
  Some tables are large and involved in a large number of transactions and I wonder if the INSERT/update performance will be seriously affected by the presence of a newspaper mview.
  
  Maybe it's a simple question, but I was unable to find an answer very clear in the literature.
  
  Thanks for all the answers!

  There is an overload for the newspapers of the view materialized, a little less, but roughly on par with a trigger that writes to a table.

  If it is an OLTP system where you do a lot of low-value transactions, the general expenses percentage is probably not particularly great, something in the range of 5-10% maybe (although, of course, by running tests in the development environment would be desirable). If there are loads in bulk, the impact of the percentage could be higher.

• Check boxes based on the table...

  I have an 'event' of the table, a "subject" of table and one table that links these two 'event_topics '. I have a form to create events and want to have all the available topics in the table of 'event' presented a list with checkboxes, to verify for each event, all the van when registering for any subject verified and relevant topics, a line is added in "event_topics" with the event_id and the topic_id.
  
  Is this possible? And if so, how do I start on this? I use Apex 3.2.

  Hello Tom,

  Yes, it is possible.

  First of all, you need a point of the box. The LOV for this element of the value to something like

  select topic_name, topic_id from topic order by topic_id
  

  To save the selection you need a process of pl/sql

  declare
    vPICKED apex_application_global.vc_arr2;
    vITEMS varchar2(1000);
    vCOUNT number;
  begin
  
    vITEMS := :YOUR_CHECKBOX_ITEM;
  
    --first delete all entries from event_topics that are not checked
    delete from event_topics
    where ':' || trim(to_char(topic_id)) || ':' not in (':' || vITEMS || ':')
    and event_id = :EVENT_ID;
  
    -- insert all new checked topics into event_topics
    vPICKED := apex_util.string_to_table(vITEMS, ':');
  
    for z IN 1..vPICKED.count
    loop
      select count(*) into vCOUNT from event_topics
      where event_id = :EVENT_ID
      and topic_id = vPICKED(z);
  
      if vCOUNT = 0 then
        insert into event_topics values (:EVENT_ID, vPICKED(z));
      end if;
    end loop;
  
  end;
  

  To extract the items all turned on during the loading of the page, you need to load on before the process of the header:

  declare
    vPICKED apex_application_global.vc_arr2;
  begin
  
    select to_char(topicl_id)
    bulk collect into vPICKED
    from event_topics
    where event_id = :EVENT_ID
    order by topic_id;
  
    :YOUR_CHECKBOX_ITEM := apex_util.table_to_string(vPICKED, ':');
  
  end;
  

  Hope this helps,
  Dirk

• ViewStack container. Choose the view based on the variable command.

  Hi I am trying to implement in my application role-based access control.  I opted for a login screen which will compare users and passwords to a MySQL database.  on a match, I need to read the 'role' associated with each user.  I want to have different views for each Admin role with the role, that role will see views admin and users, a user discovers and so on.

  I managed with a button to change the view.selectedChild.  How can I use view.selectedChild = $var.

  As a test I used a dataGrid to give me choices.  But when I use the selectionChange like this event handler

  protected function dataGrid_selectionChangeHandler(event:GridSelectionEvent):void
                                {
                                          view.selectedChild = dataGrid.selectedItem.role;
                                }
  

  It does not change the view.

  Is it possible to use ViewStack for control of access in this way?

  SelectedChild is a point of view.  What is the role?  What is an int or a string?  I would like to map it to selectedIndex instead.

  But really, I wouldn't use ViewStack and use view States that match name role.

• Field of view based on the calculated result?

  Hello

  So far, these forums have been very helpful to me making the forms for my company. I really have 2 questions, I appreciate any help I can get!

  Question 1:

  I have a submission form we use that calculates the total price by multiplying a "Quantity" field by field "cost". However, when no value is entered, the field displays "$0.00," which is accurate, but we would prefer if field does not display anything if the price was exactly zero (we actually wants it displays negative amounts, because we add discounts deducted from our quotes). Is there a way to turn 'off' field when it is equal to $0, or modify it so that it displays nothing until it changes its value?

  Question 2:

  Can I format a field so that every word in it capitalizes the first letter in uppercase? Some companies we work with can be 3-5 words long, and he saves just our sellers boredom especially when you fill out them on an iPad.

  Thank you!

  1: use this code as the custom validation script:

  "" If (event.value == "0") event.value = "";

  2. Yes, use the following custom format script:

  If {(event.value)

  Words cut var = event.value.split("");

  var newValue = "";

  for (var i = 0; i)

  If (I! = 0) newValue += "";

  newValue += splitWords [i] .charAt (0) .toUpperCase () + splitWords [i] .substring (1);

  }

  Event.Value = newValue;

  }

  I can't guarantee that it will work on the iPad, though.

• Error definition day LOV based on the month and year

  Select ' 1 ', ' 01' day_aff union double val
  ...
  Select '29', ' 29 "double where '29' < = to_char (last_day (to_date ('01.' |)))" '02'. '.' || (((', 'dd.mm.yyyy')), 'jj') union
  Select '30', ' 30 "double where '30' < = to_char (last_day (to_date ('01.' |)))" '02'. '.' || (((', 'dd.mm.yyyy')), 'jj') union

  order by 2
  
  That works well.
  
  If I replace '02' by: P10_MONTH & P10_MONTH. or v ('P10_MONTH') and 2008 by: P10_YEAR & P10_YEAR. or v ('P10_YEAR'), I get the following error on the creation of LOV (in shared components or LOV section of the element):
  
  LOV query is not valid, a display and a return value is needed, the column names must be different. If your query contains a query online, the first CLAUSE in the SQL statement must not belong to the query online.
  
  No work around?
  
  Igor

  Hi Igor,.

  I think it's the | in the SQL that is causing the problem. You can get around this by the presence of a hidden page element which is calculated at the point of process before header which calculates the first day of the selected month.

  I did it on this page: [http://apex.oracle.com/pls/otn/f?p=35917:16]

  In addition, you can simplify your SQL statement to something like:

  SELECT LEVEL d, LEVEL r
  FROM DUAL
  CONNECT BY LEVEL <= TO_NUMBER(TO_CHAR(LAST_DAY(TO_DATE(v('P16_FIRSTDATE'),'DD/MM/YYYY')),'DD'))
  

  (P16_FIRSTDATE is the element that contains the calculated date)

• Definition of attributes based on the change of password

  Hello
  
  I have a requirement where if the administrator changes the password of a user to the IOM, I need set a particular attribute in the directory server, but if the user changes his password, I need to delete it. Could someone please tell me how can I capture that has changed the password and then set this attribute in the DS?
  
  Thank you
  PETREA

  It will give the details of the profile for the user that triggered the change of password.

  Ideally, you should plug the API code in the task where you try to define attributes in the DS.

• performance of the duties based on the table

  Hello

  I have the package with multiple functions inside, each function represents the specific verification, some or all of the controls are executed on a data set.

  New controls are implemented, they are added to the main proceedings, that's good but editing master procedure source is the disadvantage.

  What I want is to move controls run logic from graphical user interface that allows the operator disable or enable the specific check without having to edit the source.

  My first idea of a table with the function names and check toggle the flag (available from the GUI) and master procedure with prepared loop only on the controls enabled.

  Secondly, one was call to main table inside each check to find is it enabled or not.

  Anyone have an idea better?

  Hi GregV,

  Audits are functions inside the package each company represents the rule, they are run on each change committed by the user. If all controls are passed the change is allowed.

  Now, there is a change - there are several groups changing dynamically the users who should be cheeks just against little business rules.

  We must allow privileged user (Administrator of the Group) assign users to groups and chose the active business rules for them.

  I'm not a big fan of dynamic sql (first idea), so

  1. I want to create tables that define active rules for groups and user group mapping

  2. change each control function of the first table of query groups and to determine who is special rule should be enforced against this group.

  3. create a gui for admin group to manage groups and assign users.

  If it is even a good idea?

  See you soon

  I chose this way

• collection type parameter [11.2] based on the table in pipeline?

  Hello

  I have a collection of type "table of ' which is filled iteratively. (he gets the new entries more of a souce)

  I need to sort the entries in this type of collection as well as the criteria.

  My approach is to use a function table in pipeline which offers individual entries as lines for a "select from table (my_function (the_collection)).

  My problem is that I get a compilation error in this query statement:

  [Error] PLS-00382 (1209:70): PLS-00382: Dieser Lutherischen hat den falschen type-> expression is of the wrong type

  [Error] PLS-00306 (1209:51): PLS-00306: wrong Anzahl oder Typen von illuminated by von call "ma_fonction"-> wrong number or type of arguments

  [Error] ORA-00904 (1209:25): PL/SQL: ORA-00904: "my_package." "" ma_fonction "-> is not a valid identifier

  but this feature is present in the package body and declared in the package header.

  the entries in the collection are declared as record types in the package header

  the collection of parameter type is declared as 'IS THE INDEX BY a_table.varchar2_attribute%TYPE my_record_type TABLE.

  the package compiled until I added the request.

  so my questions are:

  1. What is the best way to sort the types of collection (by 2 attributes)?

  2. how to pass a parameter of type of collection to a table of pipeliened function?

  Good bye

  This approach has proved to work well.

  I created a temporary table to collect the data in. At this point, I use the MERGE statement to remove duplicates.

  I sort everything in refetching this temporary table data.
